- Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name)(-monitoring level)
- Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)(-monitoring level)
NOTE: For details about the differences between the standard and compatibility modes, see the Impacts of the Standard Mode on the Web LCT in Channel Model (OTU, Line or PID Board).

Displays the object that the PM overhead monitors.

TIM Mode
|
Only SAPI, Only DAPI, SAPI&DAPI
Default: SAPI&DAPI
Only SAPI,
Only DAPI, SAPI&DAPI, No Detection
Default: No Detection
|
Sets the mode of detecting trail trace identifier mismatch. - Only SAPI: Only the source tag of the TTI is detected. When the source tag of the TTI to be Received is inconsistent with that of the TTI Received, an alarm is reported.
- Only DAPI: Only the sink tag of the TTI is detected. When the sink tag of the TTI to be Received is inconsistent with that of the TTI Received, an alarm is reported.
- SAPI&DAPI: Both the source tag and sink tag of the TTI are detected at the same time. When the source tag or sink tag of the TTI to be Received is inconsistent with that of the TTI Received, an alarm
is reported.
- No detected: Neither the source tag or the sink tag is detected. Even if the source tag or sink tag of the TTI to be Received is inconsistent with that of the TTI Received, no alarm is reported.
|
TTI to Be Sent
|
For example: a-b-e
|
The TTI to Be Sent parameter is used to set the trail trace identifier (TTI) that should be sent of the OTN path monitoring overhead layer. NOTE: Right-click the field of the TTI to be Sent or TTI to be Received parameter and choose from the shortcut menu to copy the
overhead bytes to be sent or received. This will improve the work efficiency.
|
TTI to Be Received
|
For example: a-b-e
|
The TTI to Be Received parameter is used to define the TTI to be received at the receive end. The trail trace identifier (TTI) is a string of 64 characters,
including 15 characters used as the source access point identifier, 15 characters used as the sink access point identifier, two characters of 0s, and 32 characters that are defined by carriers. |
TTI Received
|
For example: a-b-e
|
Displays the TTI received by the port.
According to the TIM Mode attributes, the system checks the consistency between the TTI to be Received and the TTI Received to determine
whether to report an alarm.
NOTE: The value of TTI Received must be the same as the value of TTI to be Received. Otherwise, an ODUk_PM_TIM alarm
is reported.
|
LCK Insertion
|
Enabled, Disabled
Default: Disabled
|
Sets whether to turn on the LCK insertion function.
When the function is Enabled, an LCK signal is inserted to the downstream for locking the signal of the user access point. This function is often used by carriers
for a test.
|
AIS Insertion
|
Enabled, Disabled
Default: Disabled
|
Sets whether to turn on the AIS insertion function.
When the function is Enabled, an AIS signal is inserted to the downstream for indicating the signal is invalid.
|
OCI Insertion
|
Enabled, Disabled
Default: Disabled
|
Sets whether to turn on the OCI insertion function.
When the function is Enabled, an OCI signal is inserted to the downstream for indicating the signal is open connection.
|
Threshold-Crossing Threshold
|
1.0E-3, 1.0E-4, 1.0E-5
Default: 1.0E-3
|
Sets the threshold-crossing threshold for BIP8 bit errors. A threshold crossing occurs if the signal bit error rate reaches this value.
It is valid only when BIP8 Detection Mode is Poisson.
|
Degrade Threshold
|
1.0E-5, 1.0E-6, 1.0E-7, 1.0E-8, 1.0E-9
Default: 1.0E-6
|
Sets the degrade threshold for BIP8 bit errors. A signal degrade occurs if the signal bit error rate reaches this value.
The Degrade Threshold should be smaller than the Threshold-Crossing Threshold.
It is valid only when BIP8 Detection Mode is Poisson.
|
Non-Intrusive Monitoring
|
Enabled, Disabled
Default: Disabled
|
Sets whether to enable the non-intrusive monitoring function.
Non-intrusive monitoring indicates that the board monitors the overhead, however, does not handle it, thus the service is not affected.
The principles for performing
the non-intrusive monitoring are as follows: The non-intrusive monitoring is performed on the overhead that is transparently transmitted by an intermediate station. The intermediate station is not the sink end of overhead termination.
|
DEG Threshold
|
- Threshold for 1.25G level: 1-10167; default value: 3050
- Threshold for 2.5G level: 1-20420; default value: 6126
- Threshold for 5G level: 1-41012; default value: 12303
- Threshold for 10G level: 1-82025; default value: 24607
- Threshold for 40G level: 1-329491; default value: 98847
- Threshold for 100G level: 1-856387; default value: 256916
|
Sets the degraded defect (DEG) threshold, which is the bit error amount threshold.
DEG represents the degrade threshold in the BIP8 bit error threshold-crossing/degrade threshold. The difference is that BIP8 monitors the bit error rate
(BER), but DEG monitors the bit error amount.
It is valid only when BIP8 Detection Mode is Bursty.
|
DEG Detection Time
|
1-10
Default: 7
|
Sets the DEG monitoring time.
It is valid only when BIP8 Detection Mode is Bursty.
|
BIP8 Detection Mode
|
Poisson, Bursty
|
Sets the mode of detecting BIP8 bit errors. - Poisson Mode: Detects the bit error rate. It is relevant to the Threshold-Crossing Threshold and Degrade Threshold.
- Burst Mode: Detects the bit error amount. It is relevant to the DEG Threshold and DEG Monitoring Time.
|
Enable TIM Response
|
Disabled, Enabled
Default: Disabled
|
Sets whether to enable the TIM follow-up response or not. When a TIM alarm is generated at this end, an AIS alarm is inserted to services in the downstream direction. This interrupts the services in the downstream direction.
|
AIS Insertion Enabling of PLM
|
Disabled, Enabled
Default: Disabled
|
Sets whether to enable the AIS Insertion Enabling of PLM or not. After the board detects the PLM alarm, the downstream NE of the service can detect an AIS alarm.
|
AIS Insertion Enabling of MSIM
|
Disabled, Enabled
Default: Disabled
|
After the AIS Insertion of the MSIM is enabled, after the board detects the MSIM alarm, the downstream NE of the service can detect an AIS alarm.
|
AIS Insertion Enabling of VCPLM
|
Disabled, Enabled
Default: Disabled
|
After the AIS Insertion of the VCPLM is enabled, after the board detects the VCPLM alarm, the downstream NE of the service can detect an AIS alarm.
|
STAT Byte Received
|
Normal Channel signal, ODUk-LCK, ODUk-OCI, ODUk-AIS
|
Displays the STAT byte received.
|
DEG Detection Time Window(ms)
|
10, 100, 1000
Default: 1000
|
Set the interval time slice of DEG.
